The leading-log renormalization of the operators \(\textbf {C}_{6L}^{ijkl}\)  and \(\textbf {C}_{6R}^{ijkl}\)  from the GUT scale \(M_{\text{GUT}}\)  to the the \(Z\)  boson mass scale \(M_Z\)  is captured by overall scaling factors described by the coefficients \(A_{SL}\)  and \(A_{SR}\) , respectively. They read [1]}, [2]}, [3]}, [4]}:
\(A_{SL(R)}=\prod _{i=1,2,3}\prod _I^{M_Z\le M_I\le M_{\text{GUT}}}\left(\frac{\alpha _i(M_{I+1})}{\alpha _i(M_I)}\right)^{\frac{\gamma _{L(R)i}}{\sum _J^{M_Z\le M_J\le M_{\text{GUT}}}b_{iJ}}},\)
